DOROT 66-21X

Hydraulically-operated, Diaphragm-actuated, 3-way Normally Closed, Metal Relay Valve

DOROT 66-21X, is a Hydraulically-operated, Diaphragm-actuated, 3-way Normally Closed, Metal Relay Valve, designed to meet hydraulic valve control functions; especially when quick reaction time is required.
Operation principle
The relay valve body contains two seats, a fully-supported frictionless diaphragm and a guide shaft. When pressure command is applied, one disc forms a tight seal with the valve seat, and when vented, the other disc seals drip-tight.
